Oh! A MAME version. That is easy, because you would be hooking up a standard projection unit to a PC / video card. It would not be a Tempest arcade machine powering the graphics. That can be done with any PC projection system, although there might be some versions that are better than others.

EDIT: Found it! See LaserMAME...

By the way, did you get the Tubes ROM? If you are not interested, I might pick it up as a spare. The one I have is (I think) one of the originals...
